Product details

The Amphenol BERGSTIK II 79821-150HLF is a 50-position, dual-row unshrouded male header on the standard 0.100" (2.54 mm) pitch.

Compared to the 50-position 79820-150HLF, the 79821-150HLF shares the same 0.100" (2.54 mm) pitch, dual-row layout, and 30.0 µin gold plating. The difference is the contact length — the 79821-150HLF carries a 0.430" (10.92 mm) mating pin length versus the 79820's 0.318" (8.08 mm). That extra 0.112" (2.84 mm) of pin reach matters when the mating receptacle sits deeper in a shrouded housing or when the board stack-up requires a longer wipe for reliable contact.

All 50 positions are loaded; no breakaway option on this variant. The push-pull retention is standard for unshrouded headers — no latch, so the mating force comes from the contact friction alone. In high-vibration environments, a secondary retention method (adhesive or a locking receptacle) is worth planning for.

Frequently asked questions

What is the pin count of 79821-150HLF?

The 79821-150HLF has 50 positions, all loaded, arranged in two rows at 0.100" (2.54 mm) pitch with 0.100" (2.54 mm) row spacing.

Is 79821-150HLF shrouded or unshrouded?

The 79821-150HLF is unshrouded — it's a bare pin-strip header with no plastic shroud around the pins. It mates with standard IDC receptacles and crimp housings but offers no keying or polarization protection.

What is the pitch of 79821-150HLF?

The mating pitch is 0.100" (2.54 mm), with the same 0.100" (2.54 mm) row spacing — the standard footprint for DIP and IDC connectors.
